Description

Technical Field

[0001] This utility model relates to the field of fresh air units, and in particular to a drainage component for fresh air units. Background Technology

[0002] Currently, some fresh air systems on the market are integrating cooling modules, which can reduce the temperature of the air blown into the room while achieving air circulation. The cooling module produces condensate during the cooling process, which needs to be drained by a drain pump. Most current fresh air system drainage components place the drain pump inlet directly in the drip tray. The main problems during use are as follows: the drip tray has a flat bottom, while the drain pump inlet is usually some distance from the bottom of the tray. This results in some water accumulation in the drip tray, which, after evaporation, leads to high humidity inside the fresh air system, affecting the equipment's lifespan. Additionally, after prolonged operation, dust accumulates in the drip tray, and excessive dust buildup at the drain pump inlet can easily cause blockage. Utility Model Content

[0003] To overcome the aforementioned problems of existing fresh air unit drainage components, the technical problem to be solved by this utility model is to provide a fresh air unit drainage component that can reduce water accumulation in the water receiving tray and prevent blockage of the water pump inlet.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] The fresh air unit drainage assembly includes a water receiving tray inside the fresh air unit and a water pump installed in the water receiving tray. It also includes a mounting bracket, which is fixed to a partition next to the water receiving tray. The water pump is installed on the mounting bracket, and the mounting bracket is also equipped with a water level switch electrically connected to the water pump. The bottom of the water receiving tray is provided with a recess near the water pump, and a filter screen is provided around the recess. The water inlet of the water pump is located in the recess.

[0006] Furthermore, the mounting frame is a sheet metal structure, including a horizontal water pump mounting platform, a horizontally arranged first mounting wall and a vertically arranged second mounting wall located at the same end of the water pump mounting platform, and a bent wall located on the side of the water pump mounting platform that bends downward at 90°, with the end of the bent wall being a horizontal support platform; the entire mounting frame is fixed to the partition through the first and second mounting walls, the water pump is installed at the bottom of the water pump mounting platform, and the water level switch is installed on the support platform.

[0007] Furthermore, the water pump mounting platform is provided with connection holes for fixing the water pump, the first mounting wall and the second mounting wall are provided with fixing holes for connecting the partition, and the end of the support platform is provided with a U-shaped opening for fixing the water level switch.

[0008] Furthermore, the bent wall comprises two, which are respectively set on different sides of the water pump mounting platform, and a water level switch is provided on the support platform at the end of each bent wall.

[0009] Furthermore, the outer diameter of the pit is 5-10 mm larger than the outer diameter of the water pump inlet, the pit depth is not less than 10 mm, and the distance between the water pump inlet and the bottom of the pit is not less than 6 mm.

[0010] Furthermore, the filter cake enclosure is a metal cylinder with dense holes on its side wall, and the bottom of the filter cake enclosure is welded and fixed to the bottom surface of the water receiving tray.

[0011] The beneficial effects of this utility model are as follows: By setting a recess at the bottom of the water receiving tray near the water pump, and placing the water pump inlet in the recess, when the water receiving tray is installed horizontally, the water in the water receiving tray will collect in the recess. The water pump draws water from the recess, which can fully discharge the condensate and avoid excessive water accumulation in the water receiving tray, which could damage the equipment. At the same time, the filter fence around the recess can block a large amount of dust, preventing blockage of the water pump inlet and ensuring smooth drainage of condensate.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] It should be noted that if this utility model contains directional indicators such as up, down, left, right, front, and back, these terms are used to describe the relative positional relationships between components and are not specific references to the absolute positions of the components or the relationships between them. They are only used to explain the relative positional relationships and movement of the components in a specific posture. If the specific posture changes, the directional indicator will also change accordingly. If this utility model contains terms related to quantity such as "many," "multiple," or "several," these terms specifically refer to two or more.

[0018] like Figure 1 As shown, the present invention provides a fresh air unit drainage assembly, including a water receiving tray 1 located inside the fresh air unit and a water pump 2 disposed within the water receiving tray 1, and a mounting frame 3. The mounting frame 3 is fixed to a partition 4 next to the water receiving tray 1. The water pump 2 is mounted on the mounting frame 3, and the mounting frame 3 is also provided with a water level switch 5 electrically connected to the water pump 2. A recess 11 is provided at the bottom of the water receiving tray 1 near the water pump 2, and a filter screen 6 is provided around the recess 11. The water inlet 21 of the water pump 2 is located inside the recess 11. The water level switch 5 is an existing product, and its linkage control with the water pump 2 is also existing technology. The preferred control logic is that when the water level rises to the detection position of the water level switch 5, the water pump 2 is controlled to pump water; when the water level drops below the detection position of the water level switch 5, the water pump 2 is controlled to work for a period of time before stopping pumping water. The water receiving tray 1 must be installed horizontally or tilted towards the recess 11. When condensation appears in the water collection pan 1, the condensation will first collect in the pit 11. As the water level rises to contact the water level switch 5, the water pump 2 starts and pumps water out until the water level drops below the water level switch 5. The water level switch 5 triggers a delay program to stop the water pump 2 from pumping water. The specific extension time should ensure that most of the water in the water collection pan 1 is pumped away, leaving only a small amount in the pit 11, to avoid the water pump 2 from running dry.

[0019] To facilitate the installation of various components and simplify the structure, the mounting bracket 3 is preferably a sheet metal structure, such as... Figure 2As shown, the mounting bracket 3 includes a horizontal water pump mounting platform 31, a horizontally arranged first mounting wall 32 and a vertically arranged second mounting wall 33 located at the same end of the water pump mounting platform 31, and a bent wall 34 located on the side of the water pump mounting platform 31 that bends downwards at 90°. The end of the bent wall 34 is a horizontal support platform 35. The entire mounting bracket 3 is fixed to the partition 4 by the horizontal first mounting wall 32 and the vertical second mounting wall 33, which ensures the stability of the mounting bracket 3. The water pump 2 is installed at the bottom of the water pump mounting platform 31, and the water level switch 5 is installed on the support platform 35. For easy disassembly, bolt installation is preferred. Therefore, the water pump mounting platform 31 is provided with a connection hole 36 for fixing the water pump 2, the first mounting wall 32 and the second mounting wall 33 are provided with fixing holes 37 for connecting the partition 4, and the end of the support platform 35 is provided with a U-shaped opening 38 for fixing the water level switch 5.

[0020] During long-term use, the water level switch 5 may fail, posing a risk of water overflowing the receiving pan 1. Therefore, to improve the safety of unit operation, the bent wall 34 includes two units, respectively installed on different sides of the pump mounting platform 31. Each bent wall 34 has a water level switch 5 on its supporting platform 35 at its end. Both water level switches 5 are electrically connected to the water pump 2. The water pump 2 is started when either one detects a water level, and shut down when neither detects a water level. The two water pumps 2 are positioned in different directions to increase the detection range, improve the reliability of unit operation, and prevent the water pump 2 from failing to operate due to the failure of one water level switch 5.

[0021] like Figure 3 As shown, to ensure smooth water pumping by the water pump 2 and prevent the inlet 21 from being blocked, the outer diameter of the recess 11 is 5-10 mm larger than the outer diameter of the inlet 21 of the water pump 2, the depth of the recess 11 is not less than 10 mm, and the distance between the inlet 21 of the water pump 2 and the bottom of the recess 11 is not less than 6 mm. Additionally, the filter cake fence 6 is preferably a metal cylinder with densely perforated sidewalls. The filter cake fence 6 can be fixed to the bottom surface of the water receiving tray 1 by welding at the bottom, ensuring reliable connection and preventing dust from entering the recess 11 through the gap between the bottom of the filter cake fence 6 and the bottom surface of the water receiving tray 1.

[0022] This invention features a recess 11 at the bottom of the water receiving tray 1 near the water pump 2, with the water pump 2's inlet 21 placed within it. The water pump 2 draws water from the recess 11, ensuring sufficient drainage of condensate and preventing excessive water accumulation in the receiving tray 1 that could damage the equipment. The filter fencing 6 surrounding the recess 11 effectively blocks dust, preventing blockage of the water pump 2's inlet 21 and ensuring smooth condensate drainage. Two water level switches on the mounting bracket 3 control the operation of the water pump 2, improving the unit's reliability and reducing the risk of overflow from the receiving tray 1. Therefore, the entire drainage assembly has excellent practicality and application value.
